Immunohistochemical detection of bovine ruminal carbonic anhydrase isoenzyme.
Rabbits immunized with low-activity ruminal carbonic anhydrase (RCA) isoenzyme, extracted from ruminal epithelial cells isolated by digestion with trypsin, yielded anti-RCA sera which reacted specifically with bovine RCA in double agar gel diffusion and immunoelectrophoretic tests, but failed to cross-react with bovine erythrocyte CA. The localization of RCA was identified in histological sections and isolated ruminal epithelial cell preparations by indirect immunofluorescence and immunoperoxidase tests as the basal, spinosum and granulosum layers of ruminal mucous epithelium.
